Passive Infrastructure Polymers for Irreversible Interruption of Organophosphate Surface Transfer Pathways

A regime-bounded framework for eliminating secondary, surface-mediated organophosphate exposure without remediation, regeneration, or endpoint-only claims

Abstract (Regulatory-Safe)

This paper delineates a class of passive surface polymers, designed specifically for infrastructure applications, whose function is to irreversibly eliminate surface-mediated pathways for secondary human exposure to persistent organophosphate residues. The system acts exclusively at the surface–contact interface, converting trace, surface-bound organophosphate compounds into non-bioavailable, covalently immobilized fragments. The polymer does not remediate environmental sources, emit volatile byproducts, or affect upstream compound usage. All claims are strictly bounded to pathway interruption under real-world environmental cycling and are explicitly falsifiable by surface-state and residue bioactivity testing.

I. Scope and Non-Claims (Critical Boundary)

This system does not:

• Remediate or decontaminate soil, water, crops, or ecosystems
• Alter environmental transport, fate, or concentration of organophosphates
• Enable, justify, or legitimize pesticide or neurotoxin deployment
• Claim population-scale neurological or health outcome improvement
• Act as a catalyst that releases mobile or volatile reaction products

This system only:

• Interrupts surface-mediated secondary transfer of pre-existing trace residues
• Operates passively without energy input, maintenance, or user action
• Produces no volatile, extractable, mobile, or bioavailable species during service

All interpretations must respect this strict structural distinction.

II. Targeted Harm Pathway (Not Environmental Load)

This work addresses the secondary exposure route arising from the accumulation and transfer of trace organophosphate residues on built surfaces. These residues persist through sorption, mechanical contact, runoff, and aerosol resuspension, enabling repeated low-dose human re-exposure that is disproportionate to original environmental concentrations and largely ungoverned by conventional regulation.

III. Polymer Architecture (Function, Not Composition)

• Permanently crosslinked surface polymer engineered for infrastructure durability
• Covalently tethered, spatially confined phosphotriesterase-mimetic domains localized to the interface layer
• Inert structural backbone consistent with polyolefin or polyurethane-class behavior
• No mobile catalysts, additives, scavengers, or leachable components

No chemical identities, synthesis routes, or optimization strategies are disclosed or implied.

IV. Governing Mechanism (Irreversible, Non-Emissive)

Under alternating real-world exposure to oxidants, ambient moisture, and mechanical or aqueous stress:

• Surface-bound organophosphate residues contact immobilized catalytic domains
• Residues undergo irreversible hydrolytic cleavage at the interface
• Cleavage fragments are covalently immobilized within the polymer network
• Bioactivity is permanently eliminated and cannot be restored without physical destruction of the matrix
• No volatile, extractable, or mobile products are generated

The system does not regenerate, turnover, or emit reaction products.

V. Why Existing Materials Fail (Structural)

• Adsorptive surfaces allow reversible release and re-transfer
• Conventional coatings lack irreversible chemical neutralization
• Active remediation requires energy, maintenance, and regulatory intervention
• Endpoint inspection cannot distinguish latent bioactivity from true neutralization

This system enforces an irreversible surface-state transition that invalidates false clearance claims.

VI. Observable, Non-Proprietary State Change

After appropriate exposure sequencing, the following must be observable:

• Loss of parent organophosphate signature (IR/XPS/NMR)
• Presence of covalently immobilized hydrolysis fragments
• Null bioactivity confirmed by validated inhibition assays after extraction

Verification does not require access to proprietary information.

VII. Decisive Falsification (Kill Test)

The system fails if, after full exposure cycling:

• >1% recoverable, bioactive organophosphate remains
• Volatile or extractable products exceed ambient baselines
• No irreversible surface-state transition is detected

VIII. Regime Boundaries

Applies to

• Exterior infrastructure and transport surfaces
• Environments with realistic oxidant, moisture, and mechanical cycling
• Passive, maintenance-free deployment contexts

Does not apply to

• Indoor air purification or acute poisoning scenarios
• Soil, water, crop, or food remediation
• Environments lacking required environmental triggers

IX. End-of-Life and Liability Containment

At end of service, the material remains inert and non-leaching. Regeneration, if pursued, is permitted only under controlled off-site conditions. No field reactivation is implied or allowed.

X. Edge of Knowledge Judgment

This framework establishes a minimum, enforceable boundary condition under which infrastructure surfaces cannot silently harbor or transfer neurotoxic residues while remaining claim-eligible. It is not a remediation strategy, a performance guarantee, or a health outcome claim—only a physically governed interruption of a previously untracked exposure pathway.

Edge of Knowledge documents define governing constraints, not products or prescriptions. This paper remains valid until regulatory, environmental, or failure boundaries materially change.
